Has Jay Taylor been flirting with Lala? Brittany is going to get to the bottom of this...

The Vanderpump Rules gang began their Hawaiian vacay in Monday night's episode, and it looked like there may be some trouble in paradise for Jax Taylor and his girlfriend Brittany Cartwright, who recently moved from Kentucky to live with him in Los Angeles. Brittany chose to believe Jax's story that there wasn't much more than a little flirting going on with Lala Kent, even after a couple of heated discussions where the SUR hostess said otherwise.

In interviews, Jax and Scheana Shay, who, along with Kristen Doute, witnessed the SUR bartender whispering that he'd like to get more intimate with Lala, purposely downplayed the flirting. So is Jax's wandering eye something Brittany should be worried about? "Not anymore," Scheana told The Daily Dish. "In the beginning, it was a little worrying, even when we were at Lock & Key and we were all having drinks, Kristen and I kept looking at each other, like, 'What are you doing?'"

Lala and Jax Get Flirty

Jax Taylor and Lala get handsy over drinks with Scheana and Kristen.

Even though Jax was being more than flirty with Lala at the table, Kristen didn't actually think anything would come of it. "That was the Jax that loves attention, not the Jax that was going to actually cheat on Brittany, I think," Kristen told The Daily Dish. "It wasn't OK by any means, but I never took him seriously that he was actually going to act on it. It was just not pushing it away."

However, Scheana did admit that Jax wasn't completely honest with his fellow SURvers about how serious his relationship with Brittany was. "Jax also was downplaying his relationship with Brittany. He's telling Brittany, 'I love you. I want to be with you forever. Have my babies. Come to California,'" she said. "And then he's telling all of us like, 'Oh, I don't know. Like, she's still in Kentucky. If it works out, cool, but it's nothing serious.'"

But Brittany also knows how to keep Jax in line. "She cracks the whip," Kristen said. "That's the really good thing about Brittany. She doesn't let Jax get away with anything."

Brittany doesn't seem to have hit it off with Lala because of the rumors surrounding her and Jax, but she doesn't have any animosity toward Kristen, who infamously hooked up with Jax in the past. "She's aware of it, but it's not as if I'm Jax's ex-girlfriend, you know?" Kristen told The Daily Dish. "To her, it didn't matter because that was before he even met her. She's just very positive, very optimistic like that. It has nothing to do with their relationship."

And that's a good thing for Kristen and Scheana, because they said they love Brittany and the energy she brings to the Vanderpump Rules crew. "I'm, like, obsessed with her," Scheana said. "Literally, she's such a breath of fresh air in our group. Sha had never seen the show. She had no idea who any of us were, which was great because she didn't have all these preconceived notions of like, 'Oh well, you're crazy, and you're annoying, and you're this.'"

Brittany has even made Jax a better friend. "I attribute, I'd say, 99 percent of Jax's change and growing up and this newfound respect that he shows to people to him dating Brittany," Kristen said.

Both Kristen and Scheana think Jax and Brittany are in it for the long haul. "They signed a lease and got a puppy, so for Jax, that's serious," Scheana said.

Kristen added, "That can be the deathrtrap for dating a girl. Like for Jax, he kind of does that where it's like here's the key, move in with me, let's get a dog, and now let's do this. For them, it's been the opposite. It's just made them so much stronger and so much better. He parades her around. He's so proud of her. He's so excited still about their relationship."
